A job characteristics approach to explain workplace bullying

This article analyses job characteristics as antecedents of workplace bullying, in line with the early Scandinavian research tradition. Research thus far suggests a large variety of possible job related antecedents. Recent review findings and methodological criticism, however, suggests that these findings need to be treated with caution. Warr's Vitamin model is used to summarize relevant job-related antecedents of workplace bullying. All relationships are tested simultaneously in a hierarchical regression analysis, controlling for covariates. A large and heterogeneous sample of Belgian workers is used to test the hypotheses (n = 6175). The results show that task autonomy is not significantly related to bullying. In line with earlier research, role conflicts and role ambiguity are the most important antecedents. Also (lack of) participation in decision making, (lack of) skill utilization, workload, cognitive demands, changes in the job, job insecurity, and (lack of) task-related feedback are found to be directly related to workplace bullying. These findings are discussed in the light of the literature and some suggestions for practice are formulated.
